This will allow developers to make applications for small screen
Android devices. It will also make it easier for hardware
companies to use Android as the operating system on their own
wearable gadgets.

With smartphone and tablet growth slowing, tech companies are
looking at gadgets like smart watches as the next potential
growth area.

Android, until now has not been designed for small devices, so
it's consuming more battery, and it doesn't look quite
right.

Samsung tried using Android for the Galaxy Gear, its smart watch,
and the results were bad. It couldn't last very long without a
recharge. For the Gear 2, Samsung
dropped Android in favor of Tizen, its own operating system.

Pichai says the SDK is coming
out ahead of any other smartwatches so that it can get feedback
and tweak the SDK.

Android is the world's biggest operating system. It's on 80% of
all smartphones shipped, and it's on the majority of tablets
shipped. If the pattern holds, it will be on the majority of all
smartwatches and whatever other wearable gadgets ship in the
future.
